Cables Direct FB3M-LCLC-020D InfiniBand Cable 2m LC Aqua

Cables Direct FB3M-LCLC-020D | OM3 LC-to-LC Multi-Mode Cable

The Cables Direct FB3M-LCLC-020D InfiniBand/fibre optic cable 2 m LC Aqua colour is designed for short-reach data centre and enterprise network links. It uses OM3 multi-mode fibre with LC connectors. This cable suits structured cabling racks where low smoke zero halogen (LSZH) jacketing is required. Because it is aqua, it visually identifies as OM3. In practice, this aids quick patch panel management. Also, the 2 m length supports neat rack-to-switch runs.

Cables Direct FB3M-LCLC-020D InfiniBand/fibre optic cable 2 m LC Aqua colour

This specific SKU offers a 2 metre LC male-to-LC male link. The cable uses 50 µm core and 125 µm cladding. Return loss is 35 dB, with 0.3 dB insertion loss. It supports 850 nm and 1300 nm wavelengths. Because it is OM3, it is optimised for 10G links over typical rack distances. However, you should confirm your transceiver compatibility before purchase.

Slim Specs Table

Multi-Mode OM3 Performance for Short-Reach Links

OM3 multi-mode fibre is tuned for 850 nm operation. It supports 10G Ethernet over typical rack distances. Because the core is 50 µm, it balances modal dispersion and cost. This cable is aqua, which signals OM3 in structured cabling. So, engineers can identify link rating at a glance. However, OM3 is not suited for long single-mode runs. You should verify your switch SFP/SFP+ optics are OM3-rated.

Low Smoke Zero Halogen (LSZH) Jacket Safety

The jacket is low smoke zero halogen (LSZH). This reduces toxic fumes in fire events. Because it is LSZH, it suits enclosed spaces and risers. However, confirm your site’s fire safety policy accepts LSZH. Also, verify local building regulations for cable routing. So, this cable supports safer installations in offices and data halls.

LC Connectors for High-Density Patching

LC connectors offer small form-factor duplex connectivity. They suit high-density patch panels and switches. Because the connectors are male, they plug into standard LC ports. However, confirm your patch panel uses LC sockets. Also, verify polarity (A/B) for your link. So, plan your patching layout before ordering.

2 Metre Length for Neat Rack Management

The 2 m length supports rack-to-switch links. It helps maintain bend radius and airflow. Because the cable is 3 mm diameter, it is flexible. However, avoid tight kinks that increase loss. Also, leave service loops for future moves. So, this length suits most standard 19″ rack setups.

Aqua Colour for OM3 Visual Identification

The aqua colour identifies the cable as OM3. This matches industry standards for multi-mode fibre. Because of this, engineers can quickly verify link rating. However, do not rely on colour alone for certification. Also, check your documentation for correct OM3 labelling. So, this cable supports clear, compliant patching.
